Systematic interpretation of differential capacitance data

open access: yesPhysical Review E, 2015
Differential capacitance (DC) data have been widely used to characterize the structure of electrolyte solutions near charged interfaces and as experimental validation of models for electrolyte structure. Fixing a large class of models of electrolyte free energy that incorporate finite-volume effects, a reduction is identified which permits the ...

A sensitive differential capacitance to voltage converter for sensor applications [PDF]

open access: yes, 1999
There is a need for capacitance to voltage converters (CVC's) for differential capacitive sensors like pressure sensors and accelerometers which can measure both statically and dynamically. A suitable CVC is described in this paper.

Analog current-mode interfaces for differential capacitance sensing [PDF]

open access: yes, 2016
In this work, we present two analog current-mode interfaces performing differential sensor capacitance measurements through a voltage reading. The AC peak-to-peak output voltage is proportional to the measurand x that is directly related to the ...

Differential Capacitance of Room Temperature Ionic Liquids: The Role of Dispersion Forces [PDF]

open access: yes, 2010
We investigate theoretical models of room temperature ionic liquids, and find that the experimentally observed camel-shape of the differential capacitance is strongly related to dispersion interactions in these systems.

Solvent primitive model of an electric double layer in slit-like pores: microscopic structure, adsorption and capacitance from a density functional approach

open access: yesCondensed Matter Physics, 2014
We investigate the electric double layer formed between charged walls of a slit-like pore and a solvent primitive model (SPM) for electrolyte solution.

Interfacial structure and differential capacitance of ionic liquid/graphite interface : A perturbed-chain SAFT density functional theory study [PDF]

open access: yes, 2020
The perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state (EoS) was combined with the electrostatic free energy from the mean spherical approximation (MSA) theory, and applied to represent densities of pure imidazolium ionic ...
